Gree Heat Pump Install – 2.5 Years Later: My Honest Review of the Gree Flexx
It’s been over two and a half years since we installed a Gree Flexx heat pump in my mother’s Chandler, Arizona home. Now seemed like a good time to share a follow-up review—not just from her perspective as the homeowner, but also from mine as someone who’s installed a lot of these units since.
Here’s what she thinks, what we found during service checks, and my personal list of pros and cons after hands-on experience with this model.
Background: Mom’s 3rd HVAC Brand in 35 Years
My mom’s lived in her Chandler home for 35 years. It’s a two-story home, with a separate heat pump system for each floor.
- Original systems: Two builder-grade Trane heat pumps
- Downstairs replacement: Swapped years ago for a Lennox heat pump
- Upstairs system: Still running strong until summer 2023, when it finally started failing
When that upstairs Trane unit started becoming unreliable, I knew it was time to replace it—and chose the Gree Flexx.
For what it’s worth, my mom’s had firsthand experience with three different HVAC brands in this home, so her feedback carries some weight.
Mom’s Review of the Gree Flexx Heat Pump
Here’s what she had to say, almost verbatim:
- “It’s so quiet, I don’t know when it’s running.”
- “I can’t feel the air blowing on me, but it’s been very comfortable in here.”
That’s it. Simple, but exactly what you want to hear from someone with a brand-new heat pump. No complaints = high praise. It tells me the system is doing its job so well, it’s virtually invisible.
To be fair, these kinds of comments aren’t unique to Gree—they’re a hallmark of inverter-driven variable-speed systems in general. But what sets the Gree Flexx apart is how it delivers that same comfort at a much lower price than most competitors.
What We Found at the First Maintenance Visit
About four months after the installation, one of our Magic Touch service techs went out to perform a standard routine maintenance visit. Here’s what we found:
- ✅ Passed all function tests and manufacturer specs
- ✅ No abnormal vibrations, loose connections, or strange noises
- 🔧 Only issue: A minor thermostat setting adjustment
We include checkups like this on every installation, because even new systems can have early hiccups. In this case, everything looked perfect.
What I Like About the Gree Flexx
Here’s what I personally like about this model, both from a technician’s and a homeowner’s point of view:
✅ Inverter-Driven Variable-Speed Compressor
- Allows capacity modulation between 1.5 to 3.25 tons in heating mode
- Modulates from 1.5 to 3.1 tons in cooling mode
- Maintains more consistent comfort and energy efficiency
✅ Ultra-Quiet Operation
- Sound rating: Around 51 decibels
- That’s quieter than two people having a normal conversation (~60 dB)
- Among the quietest ducted variable-speed heat pumps on the market
✅ Value for the Price
- One of the lowest-priced inverter-driven ducted systems available
- Delivers high-end performance without the luxury price tag
✅ Solid Construction
- Feels well-built, doesn’t rattle, and has the same quality fit-and-finish as more expensive brands
What I Don’t Like About the Gree Flexx
Now let’s talk about the cons. These are real-world issues I’ve seen across multiple installs, and I think anyone considering this unit should know about them.
❌ Parts Availability in Phoenix
- Replacement parts are not readily available from local distributors
- That’s more on the distributor than Gree, but ultimately it affects the homeowner
- Gree needs to do a better job choosing and supporting their distribution partners
❌ Pressure Relief Valve (PRV) Failures
- There’s a known issue with the factory-installed high-pressure relief valve
- When it fails, the system loses refrigerant
- The warranty doesn’t cover refrigerant, so this ends up being a real out-of-pocket expense
- Gree hasn’t provided a solid solution to this issue yet
❌ Blower Motor Recall
- A number of early Gree Flexx units shipped with defective blower motors
- There was a recall, but Gree didn’t notify dealers—we had to figure it out ourselves
- Delayed resolution due to long lead times on replacement parts
Final Thoughts: Gree Ducted Heat Pump Summary
If I had to sum up the Gree Flexx in one word, it would be: Value.
It’s hard to beat the performance, comfort, and quiet operation this unit delivers for the price. The build quality and efficiency are solid. And if it weren’t for the distribution issues and that PRV flaw, we’d still be recommending it.
Bottom Line:
- ✅ Extremely quiet and efficient
- ✅ Great comfort from inverter-driven compressor
- ✅ Lower price than other variable-speed ducted systems
- ❌ Problematic PRV that can lead to costly refrigerant loss
- ❌ Poor parts support in Phoenix due to weak distribution
- ❌ Blower motor recall handled poorly
We’ve since stopped recommending the Gree Flexx—not because of the product, but because local parts support has become too unreliable, and that PRV issue still isn’t resolved.
Gree, If You’re Listening…
The Phoenix metro area is one of the largest heat pump markets in the country. If Gree improves their local distribution and redesigns the PRV, this model would shoot to the top of our recommendation list.
Those are relatively easy fixes—and if they’re addressed, the Gree Flexx could be a serious contender again.
